SHINGLEAMACHINE. p

Specification of Letters PatentNo. 10,284, dated November 29,1853.

- T0 all whom t may concern:

Be it known that we, ISRAEL GRAVES and CHARLES A. BOGERT, of WestDresden, in the County of Yates and State of N ew York, have inventedcertain new and useful Improvements in.l Shingle-Machines; and' we dohereby declare that-the following is a full, clear, and exactdescription of the same, reference being had to Vthe accompanyingdrawings, forming part of this specification.

Figure l, is a side elevation of the machine. Fig. 2, is a verticallongitudinal section of the same. Fig; 8, is a front elevation of themachine, and Fig. 4, is a sectional detached top view, showing theconstruction an-d arrangement of the sliding cross pieces which inconnection with the cams, which are also shown, give the lateral andother necessary movement to the saw.

Similar letters of reference in each of the several figures indicatecorresponding parts.

This invention relates to a new and useful manner of making shingles,whereby we are enabled to produce a series of shingles at everyoperation of the machine and that too in the Inost perfect manner and inthe same time that it now requires to produce one shingle in a similarstate-and Our invention consists in the employment of a gang ofStationary and movable vertical Saws hung in an ordinary `saw gate andso arranged in connection with cams or their equivalents that themovable saws will be caused, as the gate moves up and down, to have agradual lateral movement from and toward the stationary saws as thestuff is fed in and also at the same time a movement out of aparallel'line with the direction of feed communicated to them and theyconsequently caused to cut in an inclined direction, or line, instead ofin a direct line, and thereby give the proper shape4 and taper to theshingle from tip to butt as will be hereinafter described. The said' sawgate being operated vertically by a crank and the cams by means ofgearing.

which is attached fast to the saw gate and moves up and down with it,and the feed rollers being actuated by gearing arranged on thestationary part of the frame.

To enable others skilled in the' art to make and use my invent-ion Iwill proceed to describe its construction and operation.

A, A, represent the frame of the machine which may be made after'theplan shown or any more suitable.

B, B, is the saw gate which is moved vertically up and down in theordinary manner of saw mill gates, by means of a crank C, and is situatenear the center of the frame A, as seen in Fig. 2, it sliding up anddown on the guide rods a, a.

D, D, are the movable saws, and E, E, E, the stationa'rysaws, all being.hung-in the gate B; those I), it will be seen eXtend up r' and down somedistance farther than those E; the `object of this is that they may besecured in the pieces b, b, and c, c, which connect them to the slottedcross pieces or arms F, G, one at the top and the other at.. the bottomof the saw gate; the pieces I) b and c, o, are united to the cross armsF G,-

by the pins d, e, which serve as `fu'lera for Y them to turn upon. BySecuring the' movable-saws fast in the pieces b, b, and C, c, n

it will be seen that, as the pintles f, g, which are on the ends of thecrossp'ieces F, G, play around in the groovesk H, I, ofthe cams J, K,the movable saws Will-'have-a eoY slightmovement out of a parallel linewith I the moti-on of feed and consequently `will eut the butt or stufftapering or to the shape ofy shingles,'the pieces o, b, and c, c,operat-' ing. like cranks; they turning on the fulcra cZ, e, as they,are actuated by the cams through l. the cross pieces orvarms F, G, whichslide laterally back and'forth simultaneously v.with

the lateral movement of the saws.v The. grooves H, I, cut aroundain theperiphery of the camsare of the-same form as'. the

desired shingle, the notches h., i, .in the grooves serving to changethe direction of the movement of the saws .and to vturn out the tip andbutt simultaneous with the.

change effected in the lateral movement of the saws by the grooves L, M,inthe cams J K. The Isaid grooves L, M, being some- Y t loo ally out ofa parallel line with the direction of feed. The movable saws are securedin the sliding cross pieces or arms N, O; one near the top and the othernear the bottom of the Saw gate as seen in Figs. 2, 3,

and eah o f these cross pieces have a pintle j, secured in their outerlends which plays in the groovesL, M, cut in the periphery of the camsJ,=K, as seen in Figs. 2, 3, and 4c. Thus it will be seen that themovable saws are secured in two sliding crossy pieces at topandbottom-to wit: in lthose F, G, which give the saws change in mo-- tionanda slight turn from a parallel line with the feed, thereby causingthem to cut easy and to give the proper butt and tip to `the .shingleand in those N, O, which are made to slide laterally back and forth bythe. grooves L, M, and to give the saws a gradual lateral movementsimultaneous with the movements given them by the `grooves H, I, andtheir vertical action and with the feed motion to them, and to causethem to cut the stuff tapering. This arrangement of saws with theirmotions enable us to produce any desired number of shingles atV everyoperation of the machine and in a very perfect manner, for it will beevident that the saws may be of any number and,

attached to the sliding cross pieces whic connect them with the cams.

P, P are feed rollers for carrying the stud up to the saws. The toproller` P, may be controlled by springs so as to be susceptibleofyielding fordiiferent thicknesses of stuff and the lower roller P, mayhave its periphery set with sharp pointsto `facilitate feed. These feedrollers are set -in motion Vby the gearing Q,V, Figs. 2, and 3,011 byany" other more suitable.

. V W and X,represent two cog wheels and a small `pinion between'them,they' being secured on the shafts 7e, Z,which have their bearing in thesaw gate and move up and down with it, and which carry the cams J, K;thelatter being secured on an independentshaftm, which has its bearingin the saw gate. Y.

7, playing in this ratchet, it being attached to the slotted arm 0',secured on the side and near the top of the machinethis arm 0', issecured by means of a pin p, to the saw gate, `the said pin playing in aslot Aupon which the pawl rleverV turns and the cog or tooth againstwhich its end ts becomes shortened and `consequentlypressure is exertedon the'ratchet and it caused to turn the distance of a tooth.Simultaneous with this movement Aof the ratchet and the cams the feedgearing is actuated by another pawl lever 8, jointed to the verticalarms, of the cross piece t, which is connected to the arm o', and set inmotion by it asthe saw gate ,rises and falls.4 This arrangement ofgearing is very effectual in -its'operw ation and`answers the purposeverymfell; but other more suitable may be adopted if thought best. Byaltering the cam; and

grooves, other' igures, such `as chaiibacks` and fellies may be sawedout; theoperation and direction of the saws being regulated by the cams,as above described.

What we claim as our invention and desire to secure `by Letters Patent,is:-`-

A machine for sawing shingles, and which may` be adapted to sawing otherirregular shapes, constructed with 'a gang of stationary and movablesaws, arranged vertically in a saw gate `which moves up and` down; themovable saws of said gang being caused to have a graduallylateralmovement, from and toward the stationary saws, while cutting, bymeans of grooved camsL, M, which operate upon the pintle, y', of the`sliding bars, N, O, carrying .the movable saws,1and` therebycommunicate. saidy lateral movement to them, the said saws, at the sametime having a movement slightly out of a parallel line with thedirection of feed communicated to them by other cams, H, I, whichoperate upon the pintle of the sliding bars, F, Gr, the said movementscausing thestufl" to be `cut tapering, or' of 4required form,substantially as herein described.
